Diego Biurrun 0e8c6f221a avisynth: Fix a "AVISynth" vs. "AviSynth" struct name typo
Also fix some similar typos in comments and documentation.

Anton Khirnov 87c31cfd7a vf_gradfun: make config_props work properly when called multiple times. 2013-05-17 07:42:39 +02:00
Anton Khirnov 05fab5530b vf_gradfun: use the name 's' for the pointer to the private context
This is shorter and consistent across filters.

Clément Bœsch 2d66fc543b lavfi/gradfun: fix rounding in MMX code.
Current code divides before increasing precision.

Also reduce upper bound for strength from 255 to 64.  This will prevent
an overflow in the SSSE3 and MMX filter_line code: delta is expressed as
an u16 being shifted by 2 to the left. If it overflows, having a
strength not above 64 will make sure that m is set to 0 (making the
m*m*delta >> 14 expression void).

A value above 64 should not make any sense unless gradfun is used as
a blur filter.

Clément Bœsch 8b9a153ef3 lavfi/gradfun: do not increment DC pointer for odd values.
First DC is only used once otherwise. This also makes the code
consistent with ASM versions.

Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

Anton Khirnov 565e4993c6 lavfi: merge start_frame/draw_slice/end_frame
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

Mans Rullgard 568c70e79e lavfi: convert input/ouput list compound literals to named objects
A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

Anton Khirnov a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init()
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

Reinhard Tartler 737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
